Special Containment Procedures: Media and advertisements in the city of ██████, Colorado are under observation by Foundation personnel for the first stage of SCP-1456. A Foundation outpost, disguised as a call centre, has been established in the town and is operated by TF-Omega 16 “The Contestants”. The centre maintains 6090 160 unique phone numbers, all publicly listed to Agent ███████. Upon identification of instances of SCP-1456-1, the number presented is immediately called in sequence in order to intercept prize instances. Agent ███████'s listed residence and a block radius is to be monitored during active phases.

A localized media campaign designed to discourage the population from entering the contests presented by SCP-1456-1 has been running for 16 years.

Description: SCP-1456 is a series of anomalous phone-in contests advertised in print, radio, local television and billboards. The advertisements vary considerably in content, claiming to represent organizations both fictional and real presenting a contest or contests promising financial or physical prizes to winning callers. Each will predominately feature a unique phone number. Collectively, these advertisements are referred to as instances of SCP-1456-1.

Instances of SCP-1456-1 appear spontaneously with no discernible external source. Billboards and print examples appear while the medium is unobserved, affecting sets of billboards owned by the same organizations and full runs of local newspapers and periodical simultaneously. Radio and television instances appear to replace regularly scheduled, legitimate advertisements. In either case, no discrepancies have been noted by the owners or operators of the transmission medium.

Calling the number provided by SCP-1456-1 with a local phone number that has not yet been used to call in will result in a “win” or “lose” result. Lose results are a simple tone, commonly described as “harsh” or “grating”, played three times before disconnection. A win result is a chime sound followed by a male voice announcing “You've won!”. Attempting to call in multiple times with the same number will result in a continuous and increasingly loud instance of the “lose” sound, escalating with no known upper limit until the phone is disconnected.

Three days after a successful “win” result, a prize, loosely consistent with the advertised prize, will be delivered to the winner, defined as the owner of the phone number used to make the winning call. The prize appears at the residence of the winner through varying means depending on the contents, by methods both mundane and anomalous.
